What happens when we spray water-soluble “air pollution” particles to plants for 2 years? 水溶性「大気汚染」粒子を植物に2年間散布したらどうなるでしょう?

Effects of 2-years exposure to (sub-micron) ammonium sulfate particles on growth and gas exchange rates of Fagus crenata (ブナ), Castanopsis sieboldii (スダジイ), Larix kaempferi (唐松) and Cryptomeria japonica (スギ) seedlings

•No significant effect of the particles on growth was observed after 2 years.
•Net photosynthetic rates of 3 species were not significantly changed.
•Net photosynthesis of Cryptomeria japonica was relatively sensitive to (NH4)2SO4.
•Both increase and reduction in net photosynthetic rate were observed in C. japonica.

4種類の植物・樹木のうち、スギ（だけ）の光合成速度は硫酸アンモニアの散布に影響を受けていることを見出した。
